TOOL FORFORMING SELVAGED FABRIC.

Application filed August 14, 1922.

T all whom it may concern:

Be it known that 1, WILLIAM C. FIsHER, a citizen of the United States, residing at Middletown, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in a Tool for Forming Selvaged Fabric; of which I declare the following to be a full,.clear, and exact description.

The present invention relates to a fabric cutting and folding tool having particular utility in connection with the formation of single fabric, endless, strips, belts or the like, such as disclosed in my copending applications relating to an article and process filed of even date herewith, Serial No. 581,- fv i'i", Selvaged edged endless fabric, and Serial No. 581,848, Process of making selvaged edged fabrics, it being an object of the present invention to provide. a simple tool which forms a guiding means, a fabric cutting means and a selvaged edge folding means. It is apparent, however that the tool may have many other uses and the invention comprehends all uses to which the same-may be put.

A. further object of the present invention is to provide a tool of the character indicated which may be cheaply and readily manufactured and satisfactorily used in performing in a single operation, the cutting and foldingof a plurality of selvaged edges of a fabric.

Various other objects are within the scope of this invention such as relate to thearrangement of the releated elements of the structure, and to various details of construction and to economies of manufacture and numerous other features as will be: apparent from a consideration of the drawing and related description of a form of the invention which may be preferred, in which Fig. 1 is a plan view of one embodiment of the present invention.

Fig 2 is a side elevation of a similar embodiment with the cutting edge extending through the top side only.

Fig. 3 is a section on line 33 of Fig. 1 showing the cutter extending on both sides of the tool.

Fig. 4: is a perspective view of the forward end of the tool.

Fig. 5 is a modification showing means Serial No. 581,849.

for applying a sizing; to the folded edge portions of the fabric.

Fig. 6 is a sectional view similar to Fig. 8, showing a modified arrangement.

Referring to the drawings, in Fig. 1, there is illustrated the body portion 10 of the tool which as shown in 3, is circular in cross-section in theparticularembodiment here illustrated, it being understood, however, that the tool may beflat, oval or oblong or of any desired shape to form on its forward end 12 a guiding and centering means for the cutting edge or wheel ofthe tool. It is understood that it is intended to usethis tool, although various other uses may be made thereof,'for the insertion in a tubular fabric which completely fills up and draws taut the threads thereof so that the cutting edge if located at the center of the tool will cut the tubular portion of the fabric at 'thecenter thereof. In Fig. 6, I show the tool located exactly at the center.

In the particular embodiment illustrated the cutting edge is in the form of a wheel 14 suitably pivoted as at 15 to the body portion 10 of the tool which is provided with a transverse opening 16, in which the cutting member 14 of the tool may be located. It is to be understood, however, that in lieu of the wheel 14 a knife edge could be properly positioned to sever the fabric upon a movement of the tool guided by the portion 12.

It is desired to fold the edges of the fabric formed bycutting the same with the wheel 1a in a peculiar manner and tothis end I have illustrated as an embodiment of a suit able folding means a plurality of sheet metal folding attachments 20, 21, 22and 23, the forward edge of'which is located adjacent the point at which the cutting wheel 14 severs the fabric. The folding attachment for example may be formed-by a thin sheet metal plate 25 folded as indicated at 26 reverselyupon, but spaced from. itself as at 27 and again folded as at 28 to terminate in a further reversediportion 29 to form a curved passage 30 through which the fabric edge passes and is folded by the folding attachment. The folding plate groove 30 gradually tapers from end to end as shown in Fig. 4 and gradually turns the edges of the cloth and presses.

the same into folded position. By providing four folders arranged centrally of the tool as shown in Fig. 6, for example, on opposite sides of the cutter and located reversely one with respect to the other it will be seen that both the upper and lower facing or surfaces of the tubular portion of the fabric is cut centrally to form four edges each of which is folded inwardly to form one selvaged edge of two pieces of fabric, it being understood, however, that any number of edges as desired may be folded by proper arrangement of the folding grooves 30 as for example one pair only of folders may be used. In Fig. 3, the width of the plates 20 and 21 make the width of the inturned edge of the top ply the same as that of the lower ply which is folded by the lower folders 22 and 23.

In Fig. 5 I have illustrated a modification of the invention in which means for applyinga sizing to the folded portions of the edge of the fabric is connected therewith. Thus I have illustrated a reservoir 32 located adjacent the handle 33 of the tool while a tube 84 connects the reservoir and extends along the tool to connect with the passage 35 through the body portion of the tool, terminating in the exterior surface thereof as indicated at 36. The tool may be provided with a similar passage 35 terminating in an opening 36 to apply a sizing to the fabric adjacent each side of the cutting wheel 1 so that each selvaged turned in edge portion may be glued as the tool is past along in the operation of cutting the fabric, folding the cut edges to form inturned edges for a plurality of strips as will be understood.

It is apparent that, within the spirit of the invention modifications and different arrangements may be made other than as herein disclosed, and the present disclosure is illustrative merely, the invention coinprehending all variations thereof.

Having thus described my invention what i desire to secure by Letters Patent of the l nited States and claim is 1. A. fabric cutting and folding tool comprising a guiding portion, a cutting edge mounted on said tool rearwardly of said guiding portion, and a fabric folding means located in said tool adjacent and rear *ardly of said cutting edge.

2. A fabric cutting and folding tool comprising a guiding portion, a cutting edge mounted on said tool rearwardly of said guiding portion, and a plurality of reversely arranged fabric folding plates located on said tool adjacent to and rearwardly of said cutting edge.

3. A fabric cutting and folding tool comprising a guiding portion, a cutting edge mounted centrally on said tool rearwardly of said guiding portion, adapted to simultaneously cut a tubular fabric along each side thereof to form four edges, and a fabric folding means located in said tool adjacent and rearwardly of said cutting edge to simultaneously fold adjacent edges inwardly and toward each other.

4. A fabric cutting and folding tool comprising a guiding portion, a cutting edge mounted on said tool rearwardly of said guiding portion, a fabric folding means located in said tool adjacent and rearwardly of said cutting edge, and a size applying means carried by, said tool.

5. A fabric cutting tool for cutting a tubular piece of fabric comprising a body having a guiding portion, adapted to fill said tubular portion of the fabric, and a cutting edge mounted on said tool rearwardly of said guiding portion.

6. A fabric cutting and folding tool comprising a guiding portion, a cutting edge mounted on said tool, and a fabric folding means located in said tool rearwardly of said cutting edge.

7. A fabric cutting and folding tool comprising a guiding portion, a cutting edge mounted on said tool and a fabric folding means located on said tool adjacent said cutting edge.

8. A fabric cutting and folding tool comprising a guiding portion, a cutting edge mounted on said tool, adapted to simultaneously cut a tubular fabric along two opposite faces on each side thereof to form four free edges, and a fabric folding means located in said tool adjacent said cutting edge to simultaneously fold adjacent edges inwardly and toward each other to form pairs of folds on opposite sides of the line out by said cutting edge.

9. A fabric cutting and folding tool comprising a guiding portion, a cutting edge mounted on said tool rearwardly of said guiding portion, and a fabric folding means located in said tool adjacent and rearwardly of said cutting edge, said guiding means adapted to form means to draw a fabric taut, said cutting edges being centrally located with respect thereo.

In testimony whereof, I afiix my signature.

WILLIAM C. FISHER.
